tb'orhly remove@ rbcrirgigngeer it; desired to ope' the' binder, hlfte reglage 2 lking" .i' the direction indicated by bled Withnthe 11S/hal notches the back 1 is Secured in .previ apart by means to be presently described. lt will be observed by reference toFigure2 of drawings that the covers 2 -are hingedly connected as at 16 to the upper edges of the wings 10 of the side members 8.`

.ln order that the loose leaves to be bound may be retained within the binder, leafsup porting posts are providedand each of these posts, which is indicated in generahby the numeral 17, comprises a tubular section 18 which is exteriorly cylindrical. 'E'ach post further comprises a section 19 which'i'sslidably telescopic-ally fittedV into the respective post section 18. At their relatively.'renfote ends, the post sections 18 and 19 are secured to bars 20 which are supported by `brackets 21 in turn secured to the inner sidesbf 'the wings 10 of the two side members 8 1 It will now be evident that when'theside'ne'm'- bers 8 are relatively separated, theclo'ose `leaves may be engagedlon theposts after which the side members Sareagain brought together. Likewise .in removingnthe leaves the sections will be' relatively separate'dffaiid the leaves will be slipped Aolf 'from' `'the posts. It will be observed by reference to Figure 2 of the drawings that the brackets 21' areoifset in an inward directiony so as to accommodate the inner or hinged edges'of 4thel covers 2 when thecovers areclQSed. y

In connection wi h the sidevmemb'e'r's 8, the invention contemplates thel provisionfb'f means for locking these membersag'aiiist separation when they yare brought toward each other in closing the binder, and theprovision of other meansfor automatically forcing the members apart when the locking means isreleased. The locking means comprises a ratchet wheel 22 which is rotatably mounted upon a stub spindle 23 upon'the upper or inner side of the back plate 5- preferably at a point midway betweenl the, ends of said plate. The links 24t'are pivotally connected as at 25 to the ratchet -wheel 2 2 'at diametrically opposite points and -at their opposite ends are pivoted as at 2,6 each toa respective one of the side members 8. lThfe links 24 extend substantially tangentially with respect to the ratchet wheel '22 and t will therefore he evident thatwhen the side members 8 are respectively adjusted, tlie link connections 24 will iinpartgrtarymotion tothe ratchet wheel 22. A Theteethif the ratchet wheel are yindicated the 'numeral 27 and extend in aseries part Way aboutv the periphery of the ratchet wheel, and in connection with the ratchet there is provided a pawl indicated in general by the numeral 28, the pawl being -pivotally mounted as at 29 upon the upper or inner 4face of the back plate 5 and being provided at onel side of its pivot with a tooth 30 for coaction with the teeth 27 of the ratchet wheel 22. b At the other side of its pivot the pawl is extended to provlde a finger lever extends longitudinally ofy the back plate 5 and-.wrks-.tliroiigh afslotf132 V'formed `in one of the end'pieces 6 ofthe said back plate, the lever 31 having its portion which projectsjbeyond,` the end of the back plate formed to provide a finger piece 33. A spring 134 is connected at one end of the back plate 5 and at its other end to the lever 31 andwyieldablyfhold's the lever in position with the tooth 3Q engaging the teeth 27. It will now be evident'that,- when thebinder is closed by fo'rcingtheside members 8' Itoward eachother, the ratchet wheel 22 will be rotated and fthe teeth 27 thereof Will ride" past the v-toothmuntil, when the ratchet wheel has ceased :to' rotate,lthe, said tooth`30 will' remain -in'locking engagement with one of; the teeth 27 and as the ratchetlwheel Vis thus -restrainedfagainst backward rotation, the side spring B11-'to 'sub'stanti l'lly'k lie dotted line o The expandingl,'rhe ans above [referred lto comprises ,tiro4 cri-,mere coiled Springs' 3,5 which are fittedat ltheir endsA over posts v36 and wh'ichbear'at their opposite ends' against ,the said ,wings As thesprings arenormally nn'der compression, their `tendency `to expand willserveto force the Kside members 8 Aapart the the pawl 2 8 gis actuated vention it will be seen that there is prov'ideda binderfinto which the leaves .may be readily; introduced andwhch binder .will
